I mean it's pretty common, no doubt. We have a lot of new players with expansion and new content, people leveling up their alts (characters or classes), people coming back from long breaks, etc. And you also have to consider people like me who already have all 3 tanks at 70, I don't run dungeons or even 24-mans on my tanks. I raid on tank so when I wanna do other stuff I just play as dps. So instead of getting pro tanks you're left with people learning or just leveling up lol
